Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BS3BA1

This summary comes from the ClinGen Evidence Repository: The c.506G>A (p.Arg169Gln) missense variant has been reported in the literature many times as the Penb antigenic epitope. However, this polymorphism has not been reported in association with Glanzmann thrombasthenia. It is present in a Latino control population at an allele frequency of 0.01439 and functional studies in CHO cells have shown no deleterious effect on surface expression or fibrinogen binding. In summary, this variant meets criteria to be classified as benign for GT. GT-specific criteria applied: BA1, BS3.

Genes affected

ITGB3 (HGNC:6156): (integrin subunit beta 3) The ITGB3 protein product is the integrin beta chain beta 3. Integrins are integral cell-surface proteins composed of an alpha chain and a beta chain. A given chain may combine with multiple partners resulting in different integrins. Integrin beta 3 is found along with the alpha IIb chain in platelets. Integrins are known to participate in cell adhesion as well as cell-surface mediated signalling. [provided by RefSeq, Jul 2008]

Glanzmann thrombasthenia

Benign:2

Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Apr 27, 2017	This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to rule this variant out of causing disease. Therefore, this variant is classified as benign. -
Benign, reviewed by expert panel	curation	ClinGen Platelet Disorders Variant Curation Expert Panel, ClinGen	Aug 07, 2019	The c.506G>A (p.Arg169Gln) missense variant has been reported in the literature many times as the Penb antigenic epitope. However, this polymorphism has not been reported in association with Glanzmann thrombasthenia. It is present in a Latino control population at an allele frequency of 0.01439 and functional studies in CHO cells have shown no deleterious effect on surface expression or fibrinogen binding.
